About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-30
The AirTAC SAIJ200X900-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. It provides a usable travel window of 870 to 900 mm, allowing you to dial back the 900 mm nominal stroke by up to 30 mm during commissioning without adding external stops. Built with an extruded aluminum barrel, it delivers massive thrust up to 28274 N at 0.9 MPa, making it suitable for heavy-duty press operations.
This 200 mm bore unit incorporates a robust 40 mm carbon steel rod with an M36x2 thread, engineered to handle substantial side loads. It operates at speeds of 30-500 mm/s and features variable air cushions at both ends to manage kinetic energy. The adjuster functions strictly as a travel stop for deceleration, not a load-holding lock; for position retention without live air pressure, a SAIL or BSAI variant is required.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-30 Is Used
Heavy Press Tuning
Dial in the exact 870-900 mm end position for large stamping presses without machining custom spacers.
Product Changeover
Quickly adapt machinery for different large-component sizes by adjusting the stroke stopper on the fly.
Automated Assembly
Provide precise end-of-stroke positioning for heavy robotic assembly lines using the 40 mm rod and M36x2 thread.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-30 the Right Cylinder?
Select this model when an application requires immense push force, as stepping down to a 160 mm bore yields 18095 N at 0.9 MPa. The adjustable stroke is ideal for product changeovers, letting operators fine-tune the retract end-stop on the fly instead of swapping the entire cylinder. To match this ISO 15552 footprint for a direct replacement, verify the 900 mm stroke, 30 mm adjustment, PT G3/4 port, and standard carbon steel rod. Because the stroke is 900 mm, an external guide is strongly recommended to prevent rod bending under offset loads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-30 FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective travel from 900 mm down to 870 mm. It does not lock the load without live air pressure.
